You’ve heard of getting rid of old CDs you don’t want but how about those pesky MP3s that take up hard drive space that you never listen to? Rather than send them to the recycle bin, Redigi.com asked a different question. What if you could sell them to others?

Redigi calls itself the “online music marketplace for used digital music” and offers music fans the ability to buy music from other users at a knockdown price and to sell MP3s that they don’t want. One big problem though… the music industry aren’t happy. Major label EMI have decided to sue and the Recording Industry Association of America (RIAA) have also sent a cease and desist letter to the company citing major copyright infringements.

It’s easy to see why. Redigi claims to be a legitimate service and that no copying takes place saying their technology is “far superior” to any others. But the copying of digital files certainly seems to be taking place in each transaction on the site. Whether a person uploads the MP3 to an intermediary server before it is bought, it’s still copied in one form or another and the law is unclear on digital goods. Redigi have said they will fight the lawsuit “vigorously’. Meanwhile, I would like to fight them for choosing that awful name.

Besides, social behemoths Facebook are continuing their plan to make music more social, so MP3s, nay recycled ones may be ripe for deletion in future. Last week, they launched the ‘Listen With Friends’ feature, which means if you use any of the current streaming music services like Spotify and Deezer, you can invite a friend to listen at the same time and shoot the breeze over chat. The move also challenges the popularity of Turntable.FM, the DJing chatroom that rose to prominence last year.
